Beginners • Re: mariadb: insert into error: thinks a variable in the values list is a column

I am trying to insert data into a mariadb table (data) via a python script using the following command:

cur.execute(" INSERT INTO data( name, value, mod_date) VALUES( 'temperature', temp_value, current_time )")

I get the following error message: Error writing data: Unknown column 'temp_value' in 'field list'

It does recognize current_time as a value.

If I change temp_value to a string, like '32', the INSERT works.
Also, if I change 'temperature' to a variable, temperature, it thinks its a column name.

Below is a description of the table, data:

Code:

MariaDB [sensor1]> describe data;+----------+-------------+------+-----+---------+----------------+| Field    | Type        | Null | Key | Default | Extra          |+----------+-------------+------+-----+---------+----------------+| id       | int(11)     | NO   | PRI | NULL    | auto_increment || name     | varchar(50) | NO   |     | NULL    |                || value    | varchar(50) | YES  |     | NULL    |                || mod_date | date        | YES  |     | NULL    |                |+----------+-------------+------+-----+---------+----------------+

Much appreciation from this Newbe!
